Fault Diagnosis Expert System for Fiber Optical Current Transducer Based on Failure Mode and Effect Analysis and Fault Tree
摘要
Abstract
Fiber optical current transducer(FOCT)is widely used in power systems,and its operational reliability can be greatly improved through fault diagnosis and analysis. Based on the fault data of FOCTs,a fault mode and effect anal?ysis(FMEA)table,a fault tree,and a fault feature space are constructed. A fault diagnosis expert system is built based on the FMEA table,fault tree and clustering center of fault feature space,thus realizing the accurate diagnosis of fault type,mode,and parts. The fault data and fault cases of FOCTs in a regional power grid were used to validate the proposed method,and results showed that the diagnosis results of the fault FOCTs based on the proposed fault diagnosis expert system were consistent with the actual on-site result. Therefore,the method proposed in this paper is accurate and reliable.关键词
